Update the Kernel to at least 2.4.24,
but better 2.4.27 from Sarge or
<http://www.backports.org/>

My FileServers and my PostgreSQL are running Woody and I have

I am transfering backups and projects between my three Workstations and
the three FileServers and transfering the compressed pg_dump's from my
PostgreSQL Server to the FileServers...
Filesize between 40 and 80 GByte.
No problem since 2.4.24 with ext3.
Please note, that ext2 is limited to 2 GByte and xfs/reiserfs
have some stange issues had in the past with older kernels.
